Abstract

Tumor-derived DNA from a non-Hodgkin's (T cell) lymphoma patient, assayed by NIH3T3 transfection followed by inoculation of cells into nude mice, was found to contain an activated N-ras proto-oncogene. The mode of activation was determined by hybridization with N-ras-specific oligonucleotide probes detecting mutations at codons 12, 13 and 61. A transversion in codon 13 (GGT----TGT) resulting in replacement of glycine13 by cysteine13 in ras p21 protein was found. The mutation was detected in DNA from mouse tumors induced by transfected NIH3T3 cells and in DNA from patient tumor lymphoblasts. The patient was heterozygous for this mutation. These data identify the first base of codon 13 as a novel mutation site in ras genes and indicate that cysteine at position 13 of the ras p21 is a transforming substitution.
